Fix Connection Problem Or Invalid MMI Code Error On Android | Real Solutions

[@paritoshkumarpramanick8313]

I faced the same issue and solved after applying a UA-cam suggestion. Dial *#21# , this will say "MMI code started" and a popup will come, click OK. After this step the problem should be fixed as it happened with my phone.
